NEW YORK (Reuters) - Stocks have been on a tear in January, moving major indexes within striking distance of all-time highs. The bearish case is a difficult one to make right now.

Earnings have exceeded expectations, the housing and labor markets have strengthened, lawmakers in Washington no longer seem to be the roadblock that they were for most of 2012, and money has returned to stock funds again.

The Standard & Poor's 500 Index has gained 5.4 percent this year and closed above 1,500 - climbing to the spot where Wall Street strategists expected it to be by mid-year. The Dow Jones industrial average is 2.2 percent away from all-time highs reached in October 2007. The Dow ended Friday's session at 13,895.98, its highest close since October 31, 2007.

The S&P has risen for four straight weeks and eight consecutive sessions, the longest streak of days since 2004. On Friday, the benchmark S&P 500 ended at 1,502.96 - its first close above 1,500 in more than five years.

"Once we break above a resistance level at 1,510, we dramatically increase the probability that we break the highs of 2007," said Walter Zimmermann, technical analyst at United-ICAP, in Jersey City, New Jersey. "That may be the start of a rise that could take equities near 1,800 within the next few years."

The most recent Reuters poll of Wall Street strategists estimated the benchmark index would rise to 1,550 by year-end, a target that is 3.1 percent away from current levels. That would put the S&P 500 a stone's throw from the index's all-time intraday high of 1,576.09 reached on October 11, 2007.

The new year has brought a sharp increase in flows into U.S. equity mutual funds, and that has helped stocks rack up four straight weeks of gains, with strength in big- and small-caps alike.

That's not to say there aren't concerns. Economic growth has been steady, but not as strong as many had hoped. The household unemployment rate remains high at 7.8 percent. And more than 75 percent of the stocks in the S&P 500 are above their 26-week highs, suggesting the buying has come too far, too fast.

MUTUAL FUND INVESTORS COME BACK

All 10 S&P 500 industry sectors are higher in 2013, in part because of new money flowing into equity funds. Investors in U.S.-based funds committed $3.66 billion to stock mutual funds in the latest week, the third straight week of big gains for the funds, data from Thomson Reuters' Lipper service showed on Thursday.

Energy shares lead the way with a gain of 6.6 percent, followed by industrials , up 6.3 percent. Telecom , a defensive play that underperforms in periods of growth, is the weakest sector - up 0.1 percent for the year.

More than 350 stocks hit new highs on Friday alone on the New York Stock Exchange. The Dow Jones Transportation Average recently climbed to an all-time high, with stocks in this sector and other economic bellwethers posting strong gains almost daily.

"If you peel back the onion a little bit, you start to look at companies like Precision Castparts, Honeywell , 3M Co and Illinois Tool Works - these are big, broad-based industrial companies in the U.S. and they are all hitting new highs, and doing very well. That is the real story," said Mike Binger, portfolio manager at Gradient Investments, in Shoreview, Minnesota.

The gains have run across asset sizes as well. The S&P small-cap index has jumped 6.7 percent and the S&P mid-cap index has shot up 7.5 percent so far this year.

Exchange-traded funds have seen year-to-date inflows of $15.6 billion, with fairly even flows across the small-, mid- and large-cap categories, according to Nicholas Colas, chief market strategist at the ConvergEx Group, in New York.

The market has shown resilience to weak news. On Thursday, the S&P 500 held steady despite a 12 percent slide in shares of Apple after the iPhone and iPad maker's results. The tech giant is heavily weighted in both the S&P 500 and Nasdaq 100 and in the past, its drop has suffocated stocks' broader gains.

JOBS DATA MAY TEST THE RALLY

In the last few days, the ratio of stocks hitting new highs versus those hitting new lows on a daily basis has started to diminish - a potential sign that the rally is narrowing to fewer names - and could be running out of gas.

Investors have also cited sentiment surveys that indicate high levels of bullishness among newsletter writers, a contrarian indicator, and momentum indicators are starting to also suggest the rally has perhaps come too far.

The market's resilience could be tested next week with Friday's release of the January non-farm payrolls report. About 155,000 jobs are seen being added in the month and the unemployment rate is expected to hold steady at 7.8 percent.

"Staying over 1,500 sends up a flag of profit taking," said Jerry Harris, president of asset management at Sterne Agee, in Birmingham, Alabama. "Since recent jobless claims have made us optimistic on payrolls, if that doesn't come through, it will be a real risk to the rally."

A number of marquee names will report earnings next week, including bellwether companies such as Caterpillar Inc, Amazon.com Inc , Ford Motor Co and Pfizer Inc .

On a historic basis, valuations remain relatively low - the S&P 500's current price-to-earnings ratio sits at 15.66, which is just a tad above the historic level of 15.

Worries about the U.S. stock market's recent strength do not mean the market is in a bubble. Investors clearly don't feel that way at the moment.

"We're seeing more interest in equities overall, and a lot of flows from bonds into stocks," said Paul Zemsky, who helps oversee $445 billion as the New York-based head of asset allocation at ING Investment Management. "We've been increasing our exposure to risky assets."

For the week, the Dow climbed 1.8 percent, the S&P 500 rose 1.1 percent and the Nasdaq advanced 0.5 percent.

NEW ORLEANS (AP) — An effigy of NFL Commissioner Roger Goodell dangles from the front porch of a New Orleans home that is otherwise festively decorated with Saints paraphernalia.

With restaurants and bars gearing up for an influx of Super Bowl XLVII visitors, the "Refuse to Serve Roger Goodell" page on Facebook had 107 likes as of Friday.

A portrait of Goodell covers the bull's-eye on the dart board at Parkview Tavern.

And floats in the unabashedly lowbrow Krewe du Vieux parade in the French Quarter last weekend displayed larger-than-life likenesses of Goodell in acts that defy polite description.

New Orleans is celebrating the return of Saints coach Sean Payton after a season of NFL banishment as a result of the "bountygate" scandal — when the team ran a pay-for-hits program. But Goodell, who suspended Payton and other current and former Saints players and coaches last year for their roles in the system, is being ridiculed here with a vehemence usually reserved for the city's scandal-scarred politicians.

"They believe he completely used the Saints as an example of something that was going on league-wide," said Pauline Patterson, co-owner of Finn McCool's, an Irish Bar in the Mid-City neighborhood where the words "Go To Hell Goodell" are visible over the fireplace.

Some of Goodell's critics say the disarray resulting from what they believe were unfair suspensions led to the Saints' 7-9 performance this year — and a missed chance to make history.

"We had a real shot of being the first team in history to host the Super Bowl in our own stadium," Parkview Tavern owner Kathy Anderson said. "He can't give that back to us."

Goodell suspended the coaches and players after an investigation found the Saints had a performance pool offering cash rewards for key plays, including big hits. The player suspensions eventually were overturned, but the coaches served their punishments.

Mayor Mitch Landrieu is among those saying that people in this city, known for its hospitality and history, should mind their manners and remember the not-too-distant past.

"Roger Goodell has been a great friend to New Orleans, and it's a fact that he's one of the people instrumental to making sure that the Saints stayed here after Hurricane Katrina," Landrieu said in a statement. It was a reference to the days after the storm, when 80 percent of the city was underwater and the damaged Superdome became a shelter for thousands of the displaced.

Then-Commissioner Paul Tagliabue and his second-in-command, Goodell, are credited with working to keep the team from abandoning New Orleans for San Antonio.

"If not for Roger Goodell, we would not have this Super Bowl," Landrieu added. "And we will need him since we want to host another one."

Saints quarterback Drew Brees said the game is validation of everything the city's gone through to rebuild after Hurricane Katrina.

"There's no question, yeah. And I think people will see that when they come down, as soon as people come down that haven't been there in a while," Brees said Friday while in Hawaii for the Pro Bowl. "The city knows how to entertain, knows how to treat people right. The tourism industry's huge, so we're excited to host this big game. Obviously it's the biggest sporting event in the world, and the city will be ready for it."

But some are in no mood to back off when it comes to Goodell.

Anderson said she understands city leaders' desire to put their best foot forward, but that it also is important for Saints fans to be able to vent.

"Whether I have Roger Goodell's face on my dart board is not going to change anybody's mind about the Super Bowl," Anderson said.

People should not take the barbs too seriously, said Lynda Woolard, a Saints fan who has been tracking some of the barbs on social media. "Nobody's saying there should be violence against the man," Woolard said.

"It's tongue-in-cheek," Patterson agreed.

Still, some diehards are ready to put it all behind them.

Patrick Brower, owner and manager of the Dirty Coast T-shirt shop, said Friday that he's pushing black-and-gold wear at his shop, choosing to unify Saints fans without bashing the commissioner.

"We've got to look forward here," Brower said. "The more time we spend in the past, it's just not beneficial."

Archaeologists have unearthed a trove of skulls in Mexico that may have once belonged to human sacrifice victims. The skulls, which date between A.D. 600 and 850, may also shatter existing notions about the ancient culture of the area.

The find, described in the January issue of the journal Latin American Antiquity, was located in an otherwise empty field that once held a vast lake, but was miles from the nearest major city of the day, said study co-author Christopher Morehart, an archaeologist at Georgia State University.

“It’s absolutely remarkable to think about this little nothing on the landscape having potentially evidence of the largest mass human sacrifice in ancient Meso-America,” Morehart said.

Middle of nowhere

Morehart and his colleagues were using satellite imagery to map ancient canals, irrigation channels and lakes that used to surround the kingdom of Teotihuacan (home to the Pyramid of the Sun), about 30 miles (50 kilometers) from Mexico City. The vast ancient kingdom flourished from around A.D 200 to 650, though who built it remains a mystery. [In Photos: Amazing Ruins of the Ancient World]

In a now drained lake called Lake Xaltocan, around which was essentially rural farmland at the time, Morehart stumbled upon a site with evidence of looting.

When the team investigated, they discovered lines of human skulls with just one or two vertebra attached. To date, more than 150 skulls have been discovered there. The site also contained a shrine with incense burners, water-deity figurines and agricultural pottery, such as corncob depictions, suggesting a ritual purpose tied to local farming. [See images from the grisly excavation ]

Carbon dating suggested that the skulls were at least 1,100 years old, and the few dozen analyzed so far are mostly from men, Morehart told LiveScience. The researchers did not release photos of the skulls because the sacrifice victims may have historic ties to modern-day indigenous cultures.

The findings shake up existing notions of the culture of the day, because the site is not associated with Teotihuacan or other regional powers, said Destiny Crider, an archaeologist at Luther College in Iowa, who was not involved in the study.

Human sacrifice was practiced throughout the region, both at Teotihuacan and in the later Aztec Empire, but most of those rituals happened at great pyramids within cities and were tied to state powers.

By contrast, “this one is a big event in a little place,” Crider said.

The shrines and the fact that sacrifice victims were mostly male suggest they were carefully chosen, not simply the result of indiscriminate slaughter of a whole village, Crider told LiveScience.

Many researchers believe that massive drought caused the fall of Teotihuacan and ushered in a period of warfare and political infighting as smaller regional powers sprang up, Morehart said.

Those tumultuous times could have spurred innovative — and bloody — practices, Crider said.

“Maybe they needed to intensify their activities because everything was changing,” she said. “When things are uncertain you try new strategies.”

Indiana, U.S. (CNN) -- North Korea has responded to new Security Council sanctions condemning its December 12 rocket launch with a declaration that it plans a third nuclear test and more missile launches. Politically, it has made unambiguous that its "aim" is its enemy, the United States.

In this rapid reaction to U.N. sanctions, the young government of Kim Jong Un underscores what Security Council members have long known anticipated from the DPRK. Their end-game is to create a vibrant, integrated missile and nuclear weapons program that will result - as in the cases of Pakistan and India - in their being recognized as a new nuclear nation by fait accompli.

In light of DPRK defiance - and a soon to occur nuclear test - the Security Council's first set of sanctions on North Korea since 2009 may seem absurd and irrelevant. These sanctions will certainly not prevent a new DPRK nuclear test. Rather, the new sanctions resolution mobilizes regional neighbors and global actors to enforce sanctions that can weaken future DPRK programs and actions.

The utility, if not the necessity, of these Security Council sanctions are to deteriorate and disrupt the networks that sustain North Korea's programs. Chances of this degradation of DPRK capabilities have increased as the new sanctions both embolden and empower the member states who regularly observe - but do nothing about - suspicious vessels in their adjacent waterways.

The resolution provides new guidance to states regarding ship interdiction, cargo inspections, and the seizure and disposal of prohibited materials. Regarding nuclear and missile development the sanctions expand the list of material banned for trade to DPRK, including high tech, dual-use goods which might aid missile industries.

These new measures provide a better structure for more effective sanctions, by naming new entities, such as a bank and trading companies, as well as individuals involved in the illicit financing of prohibited materials, to the sanctions list. To the surprise of many in the diplomatic community - the Council authorizes states to expose and confiscate North Korea's rather mobile "bulk cash." Such currency stocks have been used in many regions to facilitate purchases of luxury goods and other banned items that sustain the DPRK elites.

Finally, the Security Council frees the Sanctions Committee to act more independently and in a timely manner to add entities to the list of sanctioned actors when evidence shows them to be sanctions violators. This is an extensive hunting license for states in the region that can multiply the costs of sanctions to the DPRK over time.

Whatever their initial limitations, the new round of U.N. sanctions serve as a springboard to more robust measures by various regional and global powers which may lead back to serious negotiations with DPRK.

Despite its bluster and short-term action plan, Pyongyang recognizes that the wide space of operation for its policies it assumed it had a week ago, is now closed considerably. To get this kind of slap-down via this Security Council resolution - when the launch was a month ago - predicts that any nuke test or missile launch from Pyongyang will bring a new round of stronger and more targeted sanctions.

Although dangerous - a new game is on regarding DPRK. Tougher U.N. measures imposed on the North generated a predictable response and likely new, prohibited action. While DPRK may be enraged, these sanctions have the P5 nations, most notably China, newly engaged. A forthcoming test or launch will no doubt increase tensions on both sides.

But this may be precisely the shock needed to restart the Six Party Talks. Without this institutional framework there is little chance of influencing DPRK actions. And in the meantime, the chances of greater degrading of DPRK capabilities via sanctions, are a sensible next best action.

PORT SAID, Egypt/CAIRO (Reuters) - At least 32 people were killed on Saturday when Egyptians rampaged in protest at the sentencing of 21 people to death over a soccer stadium disaster, violence that compounds a political crisis facing Islamist President Mohamed Mursi.

Armored vehicles and military police fanned through the streets of Port Said, where gunshots rang out and protesters burned tires in anger that people from their city had been blamed for the deaths of 74 people at a match last year.

The rioting in Port Said, one of the most deadly spasms of violence since Hosni Mubarak's ouster two years ago, followed a day of anti-Mursi demonstrations on Friday, when nine people were killed. The toll over the past two days stands at 41.

The flare-ups make it even tougher for Mursi, who drew fire last year for expanding his powers and pushing through an Islamist-tinged constitution, to fix the creaking economy and cool tempers enough to ensure a smooth parliamentary election.

That vote is expected in the next few months and is meant to cement a democratic transition that has been blighted from the outset by political rows and street clashes.

The National Defense Council, which is led by Mursi and includes the defense minister who commands the army, called for "a broad national dialogue that would be attended by independent national characters" to discuss political differences and ensure a "fair and transparent" parliamentary poll.

The National Salvation Front of liberal-minded groups and other Mursi opponents cautiously welcomed the call.

THREATS OF VIOLENCE

Clashes in Port Said erupted after a judge sentenced 21 men to die for involvement in the deaths at the soccer match on February 1, 2012. Many were fans of the visiting team, Cairo's Al Ahly.

Al Ahly fans had threatened violence if the court had not meted out the death penalty. They cheered outside their Cairo club when the verdict was announced. But in Port Said, residents were furious that people from their city were held responsible.

Protesters ran wildly through the streets of the Mediterranean port, lighting tires in the street and storming two police stations, witnesses said. Gunshots were reported near the prison where most of the defendants were being held.

A security source in Port Said said 32 people were killed there, many dying from gunshot wounds. He said 312 were wounded and the ministry of defense had allocated a military plane to transfer the injured to military hospitals.

Inside the court in Cairo, families of victims danced, applauded and some broke down in tears of joy when they heard Judge Sobhy Abdel Maguid declare that the 21 men would be "referred to the Mufti", a phrase used to denote execution, as all death sentences must be reviewed by Egypt's top religious authority.

There were 73 defendants on trial. Those not sentenced on Saturday would face a verdict on March 9, the judge said.

At the Port Said soccer stadium a year ago, many spectators were crushed and witnesses saw some thrown off balconies after the match between Al Ahly and local team al-Masri. Al Ahly fans accused the police of being complicit in the deaths.

Among those killed on Saturday were a former player for al-Masri and a soccer player in another Port Said team, the website of the state broadcaster reported.

TEARGAS FIRED

On Friday, protesters angry at Mursi's rule had taken to the streets for the second anniversary of the uprising that erupted on January 25, 2011 and brought Mubarak down 18 days later.

Police fired teargas and protesters hurled stones and petrol bombs. Nine people were killed, mainly in the port city of Suez, and hundreds more were injured across the nation.

Reflecting international concern at the two days of clashes, British Foreign Office Minister for the Middle East Alistair Burt said: "This cannot help the process of dialogue which we encourage as vital for Egypt today, and we must condemn the violence in the strongest terms."

European Union foreign policy chief Catherine Ashton urged the Egyptian authorities to restore calm and order and called on all sides to show restraint, her spokesperson said.

On Saturday, some protesters again clashed and scuffled with police in Cairo, Alexandria and other cities. In the capital, youths pelted police lines with rocks near Tahrir Square.

In Suez, police fired teargas when protesters angry at Friday's deaths hurled petrol bombs and stormed a police post and other governmental buildings including the agriculture and social solidarity units.

Around 18 prisoners in Suez police stations managed to escape during the violence, a security source there said, and some 30 police weapons were stolen.

"We want to change the president and the government. We are tired of this regime. Nothing has changed," said Mahmoud Suleiman, 22, in Cairo's Tahrir Square, the cauldron of the 2011 anti-Mubarak revolt.

Mursi's opponents say he has failed to deliver on economic pledges or to be a president representing the full political and communal diversity of Egyptians, as he promised.

"Egypt will not regain its balance except by a political solution that is transparent and credible, by a government of national salvation to restore order and heal the economy and with a constitution for all Egyptians," prominent opposition politician Mohamed ElBaradei wrote on Twitter.

The opposition National Salvation Front, responding to the Defense Council's call for dialogue, said there must be a clear agenda and guarantees that any deal would be implemented, spokesman Khaled Dawoud told Reuters.

The Front earlier on Saturday threatened an election boycott and to call for more protests on Friday if demands were not met. Its demands included picking a national unity government to restore order and holding an early presidential poll.

Mursi's supporters say the opposition does not respect the democracy that has given Egypt its first freely elected leader.

The Muslim Brotherhood, which propelled Mursi to office, said in a statement that "corrupt people" and media who were biased against the president had stirred up fury on the streets.

The frequent violence and political schism between Islamists and secular Egyptians have hurt Mursi's efforts to revive an economy in crisis as investors and tourists have stayed away, taking a heavy toll on Egypt's currency.

NEW YORK (Reuters) - Stocks have been on a tear in January, moving major indexes within striking distance of all-time highs. The bearish case is a difficult one to make right now.

AUSTIN, Texas (AP) — Lance Armstrong's lawyers say the cyclist will talk more about drug use in the sport, just likely not to the U.S. Anti-Doping Agency that led the effort to strip him of his Tour de France titles.

In a testy exchange of letters and statements revealing the gulf between the two sides, USADA urged Armstrong to testify under oath to help "clean up cycling."

Armstrong's attorneys responded that the cyclist would rather take his information where it could do more good — namely to cycling's governing body and World Anti-Doping Agency officials.

USADA's response to that: "The time for excuses is over."

The letters, obtained Friday by The Associated Press, underscore the continuing feud between Armstrong and USADA CEO Travis Tygart, the man who spearheaded the investigation that uncovered a complex doping scheme on Armstrong's U.S. Postal Service teams.

Armstrong's seven Tour de France victories were taken away last year and he was banned for life from the sport.

In an interview with Oprah Winfrey last week, Armstrong admitted doping, said he owed a long list of apologies and that he would like to see his lifetime ban reduced so he can compete again.

His most realistic avenue toward that might be telling USADA everything he knows in a series of interviews the agency wants started no later than Feb. 6.

That seems unlikely.

Armstrong attorney Tim Herman responded to USADA's first letter, sent Wednesday, by saying his client's schedule is already full, and besides, "in order to achieve the goal of 'cleaning up cycling,' it must be WADA and the (International Cycling Union) who have overall authority to do so."

By Friday night, Herman strongly suggested Armstrong won't meet with USADA at all but intends to appear before the UCI's planned "truth and reconciliation" commission.

"Why would we cooperate (with USADA)?" Herman said in a telephone interview. "USADA isn't interested in cleaning up cycling. Lance has said, 'I'll be the first guy in the chair when cycling is on trial, truthfully, under oath, in every gory detail.' I think he's going testify where it could actually do some good: With the body that's charged with cleaning up cycling," Herman said.

In its last letter to Armstrong, sent Friday evening, USADA attorney William Bock said his agency and WADA work hand-in-hand in that effort.

"Regardless, and with or without Mr. Armstrong's help, we will move forward with our investigation for the good of clean athletes and the future of sport," Bock's letter reads.

The letters confirm a Dec. 14 meeting in Denver involving Armstrong, Tygart and their respective attorneys, which is when, in Tygart's words, Armstrong should have started thinking about a possible meeting with USADA.

"He has been given a deadline of February 6th to determine whether he plans to come in and be part of the solution," Tygart said in a statement. "Either way, USADA is moving forward with our investigation on behalf of clean athletes."

The letters were sent to the AP after details about a Tygart interview with "60 Minutes," being aired Sunday, were made public.

Among Tygart's claims: Armstrong is lying when he says he didn't dope during his 2009-10 comeback.

Tygart said USADA's report on Armstrong's doping included evidence Armstrong was still cheating in those years.

The nighttime viewing capabilities of the Suomi NPP satellite are giving earth scientists new views of the planet’s surface once the sun goes down.

An image taken on Sept. 27, 2012, and released recently by NASA’s Earth Observatory, shows off the satellite’s penetrating gaze with a view of low-level, marine layer clouds off the coast of California. These clouds are invisible to technologies previously used to view nighttime scenes.

Suomi NPP, run jointly by NASA and the National Oceanic and Atmospheric Administration, took the image with its Visible Infrared Imaging Radiometer Suite (VIIRS) “day-night band,” which detects wavelengths of light from green to near-infrared. This means the satellite can spot gas flares, auroras, wildfires, city lights and reflected moonlight, according to the Earth Observatory. And add to that, low-lying clouds.

In the Suomi image, the marine layer clouds shroud the ocean along the California coast, from San Francisco to Los Angeles. You can also see the shadow of some higher-level clouds cast by moonlight onto the low clouds. Marine layer clouds are so called because they form in a sheet over the ocean as low stratus clouds. [Album: Reading the Clouds]

Here’s how it works: Winds push moist surface-level air upward, causing it to expand and cool, while at the same time a coastal California feature called the Pacific High causes higher-level air to sink towards the surface, where it warms; these opposing forces create what is called an inversion layer between the surface and upper-air masses, according to the Scripps Institution of Oceanography.

While temperatures in the atmosphere typically get cooler the further up you go, the opposite happens in the inversion layer: Air is cooler toward the bottom, where the surface air is rising, and warmer toward the top of the layer, where the upper-level air is sinking.

If the air rising from the surface cools to a point at which the moisture in it condenses out below the inversion layer, marine layer clouds are formed, bounded on the top by the bottom of the inversion layer. This explains the typically uniform height of the cloud tops. The clouds are bounded on the bottom by the point at which they reach saturation and water condenses out.

These clouds can pose a hazard to ship and air travel, according to the Earth Observatory, but detecting them has been tricky in the past because of the limits of other Earth-observing satellites. Another image of the same scene taken in thermal infrared wavelengths — the band of the light spectrum typically used by meteorologists to observe Earth’s surface at night — illustrates this.

In this image, you can only see the higher-level clouds that were casting shadows in the previous image. The marine layer clouds are too close in temperature to the ground to show up as distinct feature in these wavelengths.

The U.S. ambassador to Syria says the U.S. has provided $210 million in humanitarian aid

The assistance has to be discrete, he said, to protect workers from being targeted

Washington has also provided $35 million worth of assistance to Syria's political opposition

Ambassador: We can help, but it's up to Syrians to find their way forward

(CNN) -- It has been more than a year since the United States government withdrew its ambassador to Syria and closed its embassy in Damascus.

On Thursday, that ambassador returned to the region along with a U.S. delegation, touring a Syrian refugee camp in Turkey to bring more attention to the growing humanitarian crisis. As the civil war has intensified in Syria, hundreds of thousands of people have sought refuge in Turkey, Lebanon, Jordan and other neighboring countries.

Ambassador Robert Ford gave an exclusive interview to CNN's Ivan Watson and described what the U.S. is doing to help the refugees and the Syrian opposition.

Ivan Watson: The U.S. has given $210 million in aid (to Syria), but I think that there is a perception problem because no one can actually point at what that help is. So people conclude there is no help.

Robert Ford: The assistance is going in. It's things like tents, it's things like blankets, it's things like medical equipment, but it doesn't come in big boxes with an American flag on it because we don't want the people who are delivering it to be targeted by the Syrian regime.

The regime is going after and killing people who are delivering supplies. You see them bombing even bakeries and bread lines. So we're doing that, in part, to be discrete.

The assistance is going in ... but it doesn't come in big boxes with an American flag on it.Robert Ford, U.S. ambassador to Syria

The needs are gigantic. So even though a great deal of American materials and other countries' materials are arriving, the needs are still greater. And that's why we're going to Kuwait to talk to the United Nations and to talk to other countries about how we can talk together to provide additional assistance.

Watson: The head of the Syrian National Coalition, which the U.S. government has backed, came out with a statement very critical of the international community, saying we need $3 billion if you want us to have any say on events on the ground inside Syria. Where is that money?

Ford: (Sheikh Ahmed) Moaz al-Khatib is a good leader, and we think highly of him and we have recognized his (coalition) as the legitimate representative of the Syrian people. And, of course, he wants to get as many resources as possible because of the humanitarian conditions that I was just talking about. Especially the ones inside Syria.

But we also, at the same time, have to build up those (aid) networks I was talking about. In some cases, they start out with just a few people. We don't need just a few people, we need hundreds of people, thousands of people on the inside of Syria organized to bring these things in.

And so step by step, the Syrians, Moaz al-Khatib and his organization, need to build that capacity. We can help build it, we can do training and things like that. But in the end, Syrians have to take a leadership role in this.

Watson: Is Washington giving money to the Syrian National Coalition?

Ford: We absolutely are assisting the (coalition), with everything from training to, in some cases, limited amount of cash assistance so that they can buy everything ranging from computers to telephones to radios.

Frankly, if not for the American assistance in many cases, the activists inside Syria wouldn't be in contact with the outside world. It's American help that keeps them in contact with the outside world.

Watson: But, how much assistance has this coalition gotten from the U.S.?

Ford: So far, we've allocated directly to the coalition in the neighborhood of $35 million worth of different kinds of equipment and assistance. And over the next few weeks, couple of months, we'll probably provide another $15 million worth of material assistance.

Watson: Washington recently blacklisted Jabhat al-Nusra, the Nusra Front, calling it a terrorist organization even though inside Syria, it has attracted a lot of respect for its victories and for comparative lack of corruption compared to many rebel groups. How has blacklisting the Nusra Front helped the Syrian opposition?

Ford: We blacklisted the Nusra Front because of its intimate links with al Qaeda in Iraq, an organization with whom we have direct experience, which is responsible for the killings of thousands of Iraqis, hundreds of Americans. We know what al Qaeda in Iraq did and is still doing, and we don't want it to start doing that in Syria -- which is why we highlighted its incredibly pernicious role.

I think one of the things that our classification of Nusra as a terrorist group did is it set off an alarm for the other elements of the Free Syrian Army. There was a meeting of the Free Syrian Army to set up a unified command, (and) Nusra Front was not in that meeting -- which we think is the right thing to do. As Syrians themselves understand that Nusra has a sectarian agenda, as they understand better that Nusra is anti-democratic and will seek to impose its very strict interpretation of Islam on Syria -- which historically is a relatively moderate country in terms of its religious practices -- as Syrians understand that better, I think they will more and more reject the Nusra Front itself.

Watson: But I've seen the opposite. As I go into Syria, I hear more and more support and respect for the Nusra Front, and more and more criticism for the U.S. government each time I go back.

Ford: I think that people, Ivan, are still understanding what Nusra is. I have heard criticism from the Nusra Front from people like Moaz al-Khatib who, in Marrakesh (Morocco) in his speech, said he rejected the kind of ideology which backs up Nusra. ... We have heard that from the senior commander of the Free Syrian Army as well. And so the more people understand inside Syria what Nusra is and represents, I think they will agree that is not the group on which to depend for freedom in Syria.

Watson: Do you think the U.S. government could have done more?

Ford: I think the Syrians, as I said, are the ones who will bring the answer to the problem -- just as in Iraq, Iraqis brought the solution to the Iraq crisis, to the Iraq war. The Americans can help, and we helped in Iraq, but ultimately it wasn't the Americans. Despite our help, it was Iraqis.

In Syria, again, it has to be Syrians who find their way forward. Twenty-three million Syrians need to find their way forward. We can help, and we are helping: $210 million in humanitarian assistance, $50 million to help the political opposition get organized for the day after (Bashar) al-Assad goes. These are important bits of help. But ultimately, it's not the American help. It's the Syrians themselves.

CAIRO/ISMAILIA, Egypt (Reuters) - Egypt's armed forces deployed troops in the city of Suez early on Saturday after nine people were shot dead during nationwide protests against President Mohamed Mursi, underlining the country's deep divisions as it marked the second anniversary of the uprising that toppled Hosni Mubarak.

Eight of the dead, including a policeman, were shot dead in Suez, and another was shot and killed in the city of Ismailia, medics said. Another 456 people were injured across Egypt, officials said, in unrest on Friday fuelled by anger at Mursi and his Islamist allies over what the protesters see as their betrayal of the revolution.

Mursi said the state would not hesitate in "pursuing the criminals and delivering them to justice". In a statement, he also called on Egyptians to respect the principles of the revolution by expressing their views peacefully.

The troops were deployed in Suez after the head of the state security police in the city asked for reinforcements. The army distributed pamphlets to residents assuring them the deployment was temporary and meant to secure the city.

"We have asked the armed forces to send reinforcements on the ground until we pass this difficult period," Adel Refaat, head of state security in Suez, told state television.

Friday's anniversary laid bare the divide between the Islamists and their secular rivals.

The schism is hindering the efforts of Mursi, elected in June, to revive an economy in crisis and reverse a plunge in Egypt's currency by enticing back investors and tourists.

Inspired by the popular uprising in Tunisia, Egypt's revolution spurred further revolts across the Arab world. But the sense of common purpose that united Egyptians two years ago has given way to internal strife that already triggered bloody street battles last month.

Thousands of opponents of Mursi massed on Friday in Cairo's Tahrir Square - the cradle of the revolt against Mubarak - to rekindle the demands of a revolution they say has been hijacked by the Muslim Brotherhood, the group from which Mursi emerged.

In Suez, the military deployed armored vehicles to guard state buildings, witnesses and security sources said, as symbols of government were targeted across the country.

Street battles erupted in cities including Cairo, Alexandria, Suez and Port Said. Arsonists attacked at least two state-owned buildings. An office used by the Muslim Brotherhood's political party was also torched.

"Our revolution is continuing. We reject the domination of any party over this state. We say no to the Brotherhood state," Hamdeen Sabahy, a popular leftist leader, told Reuters.

The Brotherhood decided against mobilizing for the anniversary, wary of the scope for more conflict after December's violence, stoked by Mursi's decision to fast-track an Islamist-tinged constitution rejected by his opponents.

The Brotherhood denies accusations that it is seeking to dominate Egypt, labeling them a smear campaign by its rivals.

'LEAVE! LEAVE! LEAVE!'

There were conflicting accounts of the lethal shooting in Suez. Some witnesses said security forces had opened fire in response to gunfire from masked men.

News of the deaths capped a day of violence that started in the early hours of Friday. Before dawn in Cairo, police battled protesters who threw petrol bombs and firecrackers as they approached a wall blocking access to government buildings near Tahrir Square.

Clouds of teargas filled the air. At one point, riot police used one of the incendiaries thrown at them to set ablaze at least two tents erected by youths, a Reuters witness said.

Skirmishes between stone-throwing youths and the police continued in streets around the square into the day. Ambulances ferried away a steady stream of casualties.

Protesters echoed the chants of 2011's historic 18-day uprising. "The people want to bring down the regime," they chanted. "Leave! Leave! Leave!" chanted others as they marched towards the square.

"We are not here to celebrate but to force those in power to submit to the will of the people. Egypt now must never be like Egypt during Mubarak's rule," said Mohamed Fahmy, an activist.

There were similar scenes in Suez and Alexandria, where protesters and riot police clashed near local government offices. Black smoke billowed from tires set ablaze by youths.

In Cairo, police fired teargas to disperse a few dozen protesters trying to remove barbed-wire barriers protecting the presidential palace, witnesses said. A few masked men got as far as the gates before they were beaten back.

Teargas was also fired at protesters who tried to remove metal barriers outside the state television building.

Outside Cairo, protesters broke into the offices of provincial governors in Ismailia and Kafr el-Sheikh in the Nile Delta. A local government building was torched in the Nile Delta city of al-Mahalla al-Kubra.

With an eye on parliamentary elections likely to begin in April, the Brotherhood marked the anniversary with a charity drive across the nation. It plans to deliver medical aid to one million people and distribute affordable basic foodstuffs.

Writing in Al-Ahram, Egypt's flagship state-run daily, Brotherhood leader Mohamed Badie said the country was in need of "practical, serious competition" to reform the corrupt state left by the Mubarak era.

"The differences of opinion and vision that Egypt is passing through is a characteristic at the core of transitions from dictatorship to democracy, and clearly expresses the variety of Egyptian culture," he wrote.

Mursi's opponents say he and his group are seeking to dominate the post-Mubarak order. They accuse him of showing some of the autocratic impulses of the deposed leader by, for example, driving through the new constitution last month.

"I am taking part in today's marches to reject the warped constitution, the 'Brotherhoodisation' of the state, the attack on the rule of law, and the disregard of the president and his government for the demands for social justice," Amr Hamzawy, a prominent liberal politician, wrote on his Twitter feed.

The Brotherhood says its rivals are failing to respect the rules of the new democracy that put the Islamists in the driving seat via free elections.

NEW YORK (Reuters) - The smallest of gains gave the Standard & Poor's 500 its seventh straight winning day on Thursday, but the index failed to hold above the 1,500 line, restrained by Apple's worst day in more than four years.

Apple Inc slid 12.4 percent to $450.50 a day after it posted revenue that missed Wall Street's forecast as iPhone sales were poorer than expected.

The sharp drop wiped out nearly $60 billion in Apple's market capitalization to less than $423 billion, leaving the company vulnerable to losing its status as the most valuable U.S. company to second-place ExxonMobil , at $416.5 billion.

The S&P 500, however, managed to hit its longest winning streak since October 2006.

"The market has sent the message it is no longer driven by the whims of Apple," said Ken Polcari, director of the NYSE floor division at O'Neil Securities in New York.

The S&P 500 briefly traded above 1,500 for the first time since December 12, 2007, but failed to hold above it, indicating that momentum is waning and a pullback is in the charts.

"If the market had a little bit more excitement to it, momentum players would have jumped after it broke through 1,500. Investors know the market is a little bit ahead of itself," Polcari said.

Economic data helped buoy equities as U.S. factory activity grew the most in nearly two years in January and new claims for jobless benefits dropped to a five-year low last week, giving surprisingly strong signals on the economy's pulse.

At the same time, Chinese manufacturing grew this month at the fastest pace in about two years, while data suggesting German growth picked up boosted hopes for a euro-zone recovery.

"PMI in Asia, Europe, and obviously, here in the United States, is moving in the right direction, and that's stuff people should be excited about," Polcari said.

The Dow Jones industrial average rose 46 points or 0.33 percent, to 13,825.33 at the close. The S&P 500 inched up just 0.01 of a point, or 0 percent, to finish at 1,494.82. The Nasdaq Composite dropped 23.29 points or 0.74 percent, to end at 3,130.38, with most of that loss on Apple's slide.

The broader Russell 2000 index also hit a milestone as it closed above 900 points for the first time.

Video streaming service Netflix Inc surprised Wall Street with a quarterly profit after it added nearly 4 million customers in the United States and abroad. Netflix shares surged 42.2 percent to $146.86, its biggest percentage jump ever.

Earnings have helped drive the stock market's recent rally. Thomson Reuters data through early Thursday showed that of the 133 S&P 500 companies that have reported earnings so far, 66.9 percent have exceeded expectations - above the 65 percent average over the past four quarters.

About 6.8 billion shares changed hands on the New York Stock Exchange, the Nasdaq and NYSE MKT, below the daily average during January 2012 of about 6.93 billion shares.

Roughly five issues rose for every four that fell on both the NYSE and Nasdaq.

WASHINGTON (AP) — A federal appeals court will not reconsider a decision blocking an Obama administration effort to tighten restrictions on power plant pollution.

The U.S. Circuit Court of Appeals for the District of Columbia denied the administration‘s request for a new hearing on Thursday. The court said a majority of its eight active judges opposed rehearing the case.

A three-judge judge panel ruled in August that the Environmental Protection Agency‘s cross-state air pollution rule exceeded EPA‘s authority. The EPA had said the rule would reduce power-plant pollution that contributes to unhealthy air in neighboring states.

The appeals court panel faulted the EPA for imposing “massive emissions reduction requirements” on upwind states without regard to limits imposed by law.

A spokeswoman for the EPA, Alisha Johnson, says the agency is reviewing the decision.

STORY HIGHLIGHTS

Arthur Caplan: It would be unethical to try and clone a Neanderthal baby

Caplan: Downsides include a good chance of producing a baby that is seriously deformed

He says the future belongs to what we can do to genetically engineer and control microbes

Caplan: Microbes can make clean fuel, suck up carbon dioxide, clean fat out of arteries

Editor's note: Arthur Caplan is the Drs. William F and Virginia Connolly Mitty professor and director of the Division of Bioethics at New York University Langone Medical Center.

(CNN) -- So now we know -- there won't be a Neanderthal moving into your neighborhood.

Despite a lot of frenzied attention to the intentionally provocative suggestion by a renowned Harvard scientist that new genetic technology makes it possible to splice together a complete set of Neanderthal genes, find an adventurous surrogate mother and use cloning to gin up a Neanderthal baby -- it ain't gonna happen anytime soon.

Nor should it. But there are plenty of other things in the works involving genetic engineering that do merit serious ethical discussion at the national and international levels.

Arthur Caplan

Some thought that the Harvard scientist, George Church, was getting ready to put out an ad seeking volunteer surrogate moms to bear a 35,000-year-old, long-extinct Neanderthal baby. Church had to walk his comments back and note that he was just speculating, not incubating.

Still cloning carries so much mystery and Hollywood glamour thanks to movies such as "Jurassic Park," "The Boys From Brazil" and "Never Let Me Go" that a two-day eruption of the pros and cons of making Neanderthals ensued. That was not necessary. It would be unethical to try and clone a Neanderthal baby.

Why? Because there is no obvious reason to do so. There is no pressing need or remarkable benefit to undertaking such a project. At best it might shed some light on the biology and behavior of a distant ancestor. At worst it would be nothing more than the ultimate reality television show exploitation: An "Octomom"-like surrogate raises a caveman child -- tune in next week to see what her new boyfriend thinks when she tells him that there is a tiny addition in her life and he carries a small club and a tiny piece of flint to sleep with him.

The downsides of trying to clone a Neanderthal include a good chance of killing it, producing a baby that is seriously deformed, producing a baby that lacks immunity to infectious diseases and foods that we have gotten used to, an inability to know what environment to create to permit the child to flourish and a complete lack of understanding of what sort of behavior is "normal" or "appropriate" for such a long-extinct cousin hominid of ours.

When weighed against the risks and the harm that most likely would be done, it would take a mighty big guarantee of benefit to justify this cloning experiment. I am willing to venture that the possible benefit will never, ever reach the point where this list of horrible likely downsides could be overcome.

Even justifying trying to resurrect a woolly mammoth, or a mastodon, or the dodo bird or any other extinct animal gets ethically thorny. How many failures would be acceptable to get one viable mastodon? Where would the animal live? What would we feed it? Who would protect it from poachers, gawkers and treasure hunters? It is not so simple to take a long dead species, make enough of them so they don't die of isolation and lack of social stimulation and then find an environment that is close enough and safe enough compared with that which they once roamed.

In any event the most interesting aspects of genetic engineering do not involve making humans or Neanderthals or mammoths. They involve ginning up microbes to do things that we really need doing such as making clean fuel, sucking up carbon dioxide, cleaning fat out of our arteries, giving us a lot more immunity to nasty bacteria and viruses and helping us make plastics and chemicals more efficiently and cheaply.

In trying to make these kinds of microbes, you can kill all you want without fear of ethical condemnation. And if the new bug does not like the environment in which it has to exist to live well, that will be just too darn bad.

The ethical challenge of this kind of synthetic biology is that it can be used by bad guys for bad purposes. Biological weapons can be ginned up and microbes created that only infect people with certain genes that commonly associate with racial or ethnic groups.

Rather than worry about what will happen to real estate values should a new crop of "Flintstones" move in down the street, our public officials, religious groups and ethicists need to get serious about how much regulation the genetic engineering of microbes needs, how can we detect what terrorists might try to use, what sort of controls do we need to prevent accidents and who is going to pay if a bug turns out to cause more harm than good.

We love to think that the key to tomorrow lies in what humanity can be designed or empowered to do. Thus, the fascination with human cloning. In reality, at least for a long time to come, the future belongs to what we can do to design and control microbes. That is admittedly duller, but it is far better to follow a story that is true than one such as Neanderthal cloning that is pure, speculative fantasy.

The opinions expressed in this commentary are solely those of Arthur Caplan.

Another soccer coach linked to hazing allegations on athletic teams at Maine West High School has been suspended without pay by the district while officials pursue his dismissal.

Maine Township High School District 207 officials reached that decision on freshman boys soccer coach Emilio Rodriguez at a special board meeting Thursday night, a month after reaching the same decision on the employment of head varsity soccer coach Michael Divincenzo.

“The board believes Mr. Rodriguez violated District 207 Board of Education policy and professional expectations by failing to adequately prevent, recognize, report and punish student hazing,” board president Sean Sullivan said in a statement read at the meeting.

Both men were originally placed on paid leave and reassigned from teaching duties this fall when allegations of hazing surfaced in early October on the Des Plaines school’s soccer and baseball teams.

Those allegations are the subject of a lawsuit filed on behalf of four alleged hazing victims on the soccer team and against the district, both coaches and Maine West Principal Audrey Haugan.

Rodriguez, a tenured applied arts and technology teacher, has 17 days to request a hearing on his dismissal through the Illinois State Board of Education, officials said.

Through an attorney, Divincenzo recently requested an appeal hearing with the state board. The appeal process could take up to one year, officials said.

Rodriguez could not be reached for comment on Thursday night. But Des Plaines police reports show he and Divincenzo previously denied any knowledge of team hazing or initiation rituals.

District officials also fulfilled early promises made shortly after the hazing allegations surfaced by approving the hiring of former assistant U.S. attorney Sergio Acosta to lead the district’s independent investigation into hazing allegations, and California-based consultant Community Matters to lead focus groups studying bullying and hazing prevention techniques.

Last week, district officials confirmed the receipt of grand jury subpoenas in the Cook County state’s attorney’s ongoing investigation. Officials reiterated their commitment to “cooperate fully with all agencies conducting their own investigations, including the Cook County State’s Attorney, Des Plaines Police and the Illinois Department of Children and Family Services.

One subpoena, dated Dec. 6 and obtained by the Tribune, directs Maine West Principal Audrey Haugan to produce “personnel files, disciplinary records, reports, memorandums, summaries, interviews, investigations, notes, statements or other such writings or recordings for Michael Divincenzo and Emilio Rodriguez, and any and all other employees associated with coaching student athletes from 2007 to the present time.”

In another Dec. 6 subpoena, Superintendent Ken Wallace is directed to produce “any written materials describing or explaining” school, student athlete, coach or teacher conduct codes or rules, “or rules or any other similar such writings including but not limited to the topics of hazing, sexual misconduct or physical misconduct in any manner associated with Maine West High School.”

Wallace, Haugan, Maine East Principal Michael Pressler and Maine South Principal Shawn Messmer also received subpoenas dated Dec. 7. Those subpoenas, which were partially redacted, seek “any and all letters, emails, reports, memorandums, call logs, writings, recordings, or other such material regarding” redacted information, “including any such documents from within the school records or school file for” redacted information.

SEOUL (Reuters) - North Korea said on Thursday it would carry out further rocket launches and a nuclear test that would target the United States, dramatically stepping up its threats against a country it called its "sworn enemy".

The announcement by the country's top military body came a day after the U.N. Security Council agreed to a U.S.-backed resolution to censure and sanction North Korea for a rocket launch in December that breached U.N. rules.

North Korea is not believed to have the technology to deliver a nuclear warhead capable of hitting the continental United States, although its December launch showed it had the capacity to deliver a rocket that could travel 10,000 km (6,200 miles), potentially putting San Francisco in range, according to an intelligence assessment by South Korea.

"We are not disguising the fact that the various satellites and long-range rockets that we will fire and the high-level nuclear test we will carry out are targeted at the United States," North Korea's National Defence Commission said, according to state news agency KCNA.

North Korea is believed by South Korea and other observers to be "technically ready" for a third nuclear test, and the decision to go ahead rests with leader Kim Jong-un, who pressed ahead with the December rocket launch in defiance of the U.N. sanctions.

China, the one major diplomatic ally of the isolated and impoverished North, agreed to the U.S.-backed resolution and it also supported resolutions in 2006 and 2009 after Pyongyang's two earlier nuclear tests.

Thursday's statement by North Korea represents a huge challenge to Beijing as it undergoes a leadership transition, with Xi Jinping due to take office in March.

China's Foreign Ministry called for calm and restraint and a return to six-party talks, but effectively singled out North Korea, urging the "relevant party" not to take any steps that would raise tensions.

"We hope the relevant party can remain calm and act and speak in a cautious and prudent way and not take any steps which may further worsen the situation," ministry spokesman Hong Lei told reporters at a regular press briefing.

North Korea has rejected proposals to restart the talks aimed at reining in its nuclear capacity. The United States, China, Russia, Japan and the two Koreas are the six parties involved.

"After all these years and numerous rounds of six-party talks we can see that China's influence over North Korea is actually very limited. All China can do is try to persuade them not to carry out their threats," said Cai Jian, an expert on Korea at Fudan University in Shanghai.

Analysts said the North could test as early as February as South Korea prepares to install a new, untested president or that it could choose to stage a nuclear explosion to coincide with former ruler Kim Jong-il's Feb 16 birthday.

"North Korea will have felt betrayed by China for agreeing to the latest U.N. resolution and they might be targeting (China) as well (with this statement)," said Lee Seung-yeol, senior research fellow at Ewha Institute of Unification Studies in Seoul.

U.S. URGES NO TEST

Washington urged North Korea not to proceed with a third test just as the North's statement was published on Thursday.

"Whether North Korea tests or not is up to North Korea," Glyn Davies, the top U.S. envoy for North Korean diplomacy, said in the South Korean capital of Seoul.

"We hope they don't do it. We call on them not to do it," Davies said after a meeting with South Korean officials. "This is not a moment to increase tensions on the Korean peninsula."

The North was banned from developing missile and nuclear technology under sanctions dating from its 2006 and 2009 nuclear tests.

A South Korean military official said the concern now is that Pyongyang could undertake a third nuclear test using highly enriched uranium for the first time, opening a second path to a bomb.

North Korea's 2006 nuclear test using plutonium produced a puny yield equivalent to one kiloton of TNT - compared with 13-18 kilotons for the Hiroshima bomb - and U.S. intelligence estimates put the 2009 test's yield at roughly two kilotons

North Korea is estimated to have enough fissile material for about a dozen plutonium warheads, although estimates vary, and intelligence reports suggest that it has been enriching uranium to supplement that stock and give it a second path to the bomb.

According to estimates from the Institute for Science and International Security from late 2012, North Korea could have enough weapons grade uranium for 21-32 nuclear weapons by 2016 if it used one centrifuge at its Yongbyon nuclear plant to enrich uranium to weapons grade.

North Korea has not yet mastered the technology needed to make a nuclear warhead small enough for an intercontinental missile, most observers say, and needs to develop the capacity to shield any warhead from re-entry into the earth's atmosphere.

North Korea gave no time-frame for the coming test and often employs harsh rhetoric in response to U.N. and U.S. actions that it sees as hostile.

The bellicose statement on Thursday appeared to dent any remaining hopes that Kim Jong-un, believed to be 30 years old, would pursue a different path from his father, Kim Jong-il, who oversaw the country's military and nuclear programs.

The older Kim died in December 2011.

"The UNSC (Security Council) resolution masterminded by the U.S. has brought its hostile policy towards the Democratic Peoples Republic of Korea (North Korea) to its most dangerous stage," the commission was quoted as saying.

CORAL GABLES, Fla. (AP) — With a steady din coming from the sea of orange behind the visitors' basket, No. 1 Duke had a tough time making a shot.

The Blue Devils went more than 8 minutes without a field goal in the first half Wednesday night, and a sellout became a blowout for No. 25 Miami, which delighted a boisterous crowd with a 90-63 victory.

The defeat was the third-worst ever for a No. 1 team. The last time Duke lost a regular-season game by a bigger margin was in January 1984.

"It wasn't demoralizing; they played better," Blue Devils guard Rasheed Sulaimon said. "I believe we have them on the schedule again."

"We expected them to be terrific, and we have to match terrific, and then you have a terrific game," Duke coach Mike Krzyzewski said. "What you had was a terrific win for them, but not a terrific game. We didn't hold our end of the bargain."

Miami (14-3, 5-0 Atlantic Coast Conference) beat a No. 1 team for the first time, taking control with a stunning 25-1 run midway through the opening half. The Blue Devils missed 13 consecutive shots despite numerous good looks, while four Hurricanes hit 3-pointers during the run that transformed a 14-13 deficit into a 38-15 lead.

Duke (16-2, 3-2) fell to 0-2 when playing on an opponent's court. The Blue Devils' other loss came at North Carolina State, a defeat that cost them the No. 1 ranking.

They regained the top spot this week but seemed rattled by the capacity crowd, only the 10th in 10 years at Miami's on-campus arena. Students began lining up for seats outside the arena almost 24 hours before tipoff, a rarity for the attendance-challenged Hurricanes.

"I don't know how you can sit outside for a basketball game for that long," Miami guard Durand Scott said. "That made me want to win for them even more."

The Hurricanes, who are alone atop the league standings, won their sixth consecutive game. They beat Duke for the second straight time — but only the fourth time in the 19-game series.

Miami had been 0-6 against No. 1 teams. Coach Jim Larranaga also beat a No. 1 team for the first time.

"This is a great memory," Larranaga said.

Scott scored a season-high 25 points for the Hurricanes, and Kenny Kadji added a season-high 22. Shane Larkin had 18 points, 10 rebounds and five assists, and Durham, N.C. native Julian Gamble had 10 rebounds and four blocked shots.

Miami senior center Reggie Johnson came off the bench in his first action since being sidelined with a broken left thumb Dec. 18. He had two points and five rebounds in 16 minutes.

The Hurricanes, ranked this week for the first time in three years, improved to 8-0 at home.

Seth Curry, Tyler Thornton and Quinn Cook went a combined 1 for 29 for the Blue Devils, who shot a season-low 30 percent. Sulaimon led them with 16 points.

Duke went 4 for 23 from 3-point range, while Miami went 9 for 19 and shot 57 percent overall.

"Especially in the first couple of minutes, we got a lot of great shots," Blue Devils forward Mason Plumlee said. "You're going to miss some, but you have to keep shooting. The biggest mistake you can make is questioning your shot because you're missing open shots."

Kadji made two 3s during the Hurricanes' first-half spurt, then capped it with a three-point play. Duke shot 22 percent in the first half, including two for 11 on 3-pointers, and trailed 42-19 at halftime.

There was no letup by the Hurricanes to start the second half. They scored the first seven points for a shocking 49-19 lead, and punctuated the drubbing with five dunks in the final 10 minutes.

"Some teams come out in the second half flat and think they have the game won," Larkin said, "but we stayed with it with the same energy in the second half. We played great the whole game."

A Duke mistake — one in a long series — early in the second half had Krzyzewski red-faced and on the court, screaming at his team. But he couldn't inspire a turnaround.

"Over-rated," fans chanted with 3 minutes left. When the game ended, they poured onto the court and mobbed their team.

Back in North Carolina, fans of the Tar Heels savored the loss by their rivals. When the final score of the Duke game was posted on the video board at the North Carolina-Georgia Tech game, students chanted, "Go to hell, Duke!"
